http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10901 --- Comment #26 from Dominique d'Humieres dominiq at lps dot ens.fr 2012-01-20 16:24:34 UTC --- I have done a clean bootstrap of r183305 on powerpc-apple-darwin9 with the patch in comment #25. Regtesting in progress (allow for ~20 more hours), but gcc at -m32 has only 28 failures (including 16 for gcc.dg/simulate-thread/atomic-* instead of usually 12: I cannot say presently if it is due to some slow down due to the patch or because I am using the machine while usually it is only devoted to the test suite).

JFTR, I suspect the issue is moot in clang/llvm because they don't support nested functions AFAICT - but use 'blocks' instead. BTW, is there any access to the 'positron' branch - was it ever on an FSF server?

The positron branch should be on the Apple open source website, though, just grabbing the top of the tree (latest version of gcc-4.2) I think would be preferable. There is a version in the llvm repo, though, it does have all the llvm goop in it as well.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10901 --- Comment #25 from Iain Sandoe iains at gcc dot gnu.org 2012-01-18 18:29:12 UTC --- Created attachment 26370 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=26370 initial fix this shares some changes with the fix to PR51784 (and that is somewhere to read about the issues that prevent an easier fix). AFAICT, the bugs are still present in the Apple OS tree - at least they are with 4.2.1/5577 - which postdates the comments here. Anyway, this is a starting point - I expect that there is scope to tidy it up. As things stand we need to differentiate the load-picbase from the reload-picbase on PPC because more of the work is done in the md. On x86 it's hidden away in i386.c - which made it easier to fix there.

Still fails on both ppc-darwin and i386-darwin, for 4.3.2, 4.4.0 and current
trunk:
$ cat a.c
extern int puts (const char *);
extern void abort (void);
int main ()
{
__label__ l1;
void foo ()
{
void bar ()
{
puts (goto l1);
goto l1;
}
bar ();
}
foo ();
abort ();
l1:
puts (label l1);
return 0;
}
$ gcc -O3 a.c ./a.out
goto l1
label l1
$ gcc -O0 a.c ./a.out
goto l1
(It also fails with Apple's gcc.)
